With a smart electricity tariff like Octopus Agile or Flux, your battery charges automatically on cheap overnight electricity (typically 2–8p/kWh), then discharges during expensive peak hours (25–35p/kWh). This can add £200–£400/year in additional savings on top of the solar benefit.
How Battery Storage Works
Solar panels generate electricity during daylight
Your home uses what it needs in real time. Surplus electricity that would otherwise be exported to the grid is sent to the battery.
Battery stores surplus solar electricity
Modern lithium batteries are 95%+ efficient, retaining almost all the energy they receive. A 9.6kWh battery stores enough for a typical evening's use.
Battery discharges in the evening and overnight
As solar generation drops after 4–5pm, the battery automatically discharges to power your home. The grid only tops up when the battery is depleted.
Smart charging from overnight cheap-rate electricity
On smart tariffs, the battery can also charge from the grid during cheap overnight hours (typically 12am–5am at 7–15p/kWh).
Local Grant Support in Burwell
The Warm Homes: Local Grant, delivered in Burwell by Action on Energy Cambridgeshire — the Cambridgeshire Energy Retrofit Partnership of six councils including East Cambridgeshire District Council (Burwell's district council), with Cambridge City Council acting as lead authority — funds insulation, solar panels and air source heat pumps for lower-income households (combined income broadly under £36,000, with flexibility for those above it who struggle with energy bills) living in EPC D–G rated homes or park homes. The scheme runs until 2028 and the service is currently working at capacity, so enquiries are taking longer than normal to progress.
Battery storage qualifies for 0% VAT when installed alongside solar panels. We check your full grant eligibility during the free survey.
Why Choose Green Hat for Battery Storage in Burwell?
Burwell has no MCS-accredited solar installer based in the village itself — homeowners are typically quoted by firms travelling in from Highfields Caldecote on the far side of Cambridge (Lux Electrical), Witchford near Ely (Eco Installer), Newmarket (Projects4Renewables), Suffolk (Lectec, which markets heavily into Cambridge) or even Essex-based players like NXTGEN Energy. Yet the village sits at the literal centre of the region's solar transition: the Burwell National Grid substation is the connection point for the 2,500-acre Sunnica Energy Farm consented in July 2024, and Swaffham Prior — two miles up the road — became the first UK village to retrofit a renewable community heat network. Local demand is rising accordingly, and directory listings for the CB25 area are dominated by out-of-area firms rather than genuinely local ones.
- Green Hat's base in Isleham is around five miles from Burwell via Fordham — surveys, installs and any aftercare call-out are roughly a ten-minute drive, not a day trip from Cambridge or Essex like most firms quoting in CB25.
- Burwell's two conservation areas (High Town and North Street) both carry Article 4 Directions — two of only four conservation areas in the whole East Cambridgeshire district to do so (the others are Ely and Soham) — and we design arrays on rear roof slopes that stay within permitted development, or handle the planning application when a highway-facing slope is unavoidable.
- We know Burwell's property mix first-hand: clunch-and-pantile cottages around the Grade I listed St Mary's church at one end, and modern estate homes — including the 350-home Millstone Park development — at the other, each needing a different mounting, scaffold and design approach.
- As a fen-edge business ourselves, we work these open, exposed roofs every week and specify fixings and panel layouts for the wind loading and wide, unshaded aspects typical of the Burwell fen edge.
- Being MCS certified means Burwell households qualify for Smart Export Guarantee payments on every install, and we can help qualifying lower-income households check their eligibility for Warm Homes: Local Grant funding through Action on Energy Cambridgeshire.
Battery Storage Installation Timeline in Burwell
Because Green Hat is based in Isleham, around five miles away, a free site survey in Burwell can usually be arranged within a few days, and a standard domestic solar or battery installation takes one to two days on the roof — typically two to four weeks end-to-end from survey to commissioning. The local wrinkle is planning: Burwell's High Town and North Street conservation areas both carry Article 4 Directions, so panels on a roof slope fronting the highway need planning permission from East Cambridgeshire District Council (allow roughly eight weeks for a decision), and listed buildings such as those around St Mary's church always require listed building consent. Rear-facing roof slopes in the conservation areas, and virtually all of Burwell's modern housing, generally proceed under permitted development with no delay. Battery-only retrofits can often be scheduled faster — typically 2-3 weeks from survey to installation.
Battery Storage Coverage in Burwell
Complete Home Energy System in Burwell
Battery storage works best as part of a complete home energy system. Pair it with solar panels to capture free electricity, a heat pump to eliminate gas or oil heating, and an EV charger to drive on sunshine. In Burwell, the combined system typically reduces total energy costs by 60-80% and cuts household carbon emissions by over 4 tonnes per year.
Frequently Asked Questions — Battery Storage in Burwell
Do you install battery storage in Burwell?
Yes. Burwell is within our core service area, 4 miles from our Isleham base. We install Fox ESS, SolarEdge, and Tesla Powerwall battery storage systems for homes and businesses across Burwell and the surrounding area.
How much does battery storage cost in Burwell?
Battery storage in Burwell typically costs £2,800–£6,500 installed, depending on capacity. A 5kWh battery costs approximately £2,800–£3,800. A 9.5kWh battery costs £4,000–£5,200. All installations include 0% VAT. When combined with solar panels, the total system cost is eligible for 0% VAT until March 2027.
Can I add a battery to my existing solar panels in Burwell?
Yes. We retrofit battery storage to existing solar panel systems across Burwell. We first assess your current inverter — if it is a hybrid-ready model (Fox ESS, SolarEdge, Huawei) a battery can be added directly. Older string inverters may require an AC-coupled battery such as the Tesla Powerwall. We assess this during your free survey.
How much can I save with battery storage in Burwell?
A 9.5kWh battery added to a 4kW solar system in Burwell typically saves an additional £300–£600 per year compared to solar alone, by capturing surplus daytime generation for evening and night use. With a smart tariff like Octopus Agile, savings increase further by charging the battery on cheap overnight electricity (typically 2–8p/kWh).
Is battery storage worth it in Burwell?
Battery storage is most cost-effective when you already have or plan to install solar panels, have high evening electricity use, or can use a smart tariff. For most Burwell homeowners with solar, battery storage reduces grid dependency to under 20%, with payback typically in 7–9 years. Properties with an EV also benefit significantly — battery-charged EV charging can cost as little as 2p/mile.
How long does battery storage installation take in Burwell?
A battery storage installation typically takes 4–6 hours for a single unit. Combined solar and battery installations take 2–3 days. We can usually schedule Burwell installations within 3–5 weeks of survey. Our proximity means we prioritise same-week callouts for Burwell customers when availability allows.
What is the best battery for homes in Burwell?
The Fox ESS EVO (5–10kWh) is our most-installed battery for Burwell homes. It uses modular LiFePO4 chemistry with smart tariff integration and a 10-year warranty. For homes with existing SolarEdge inverters, the SolarEdge Energy Bank is the natural pairing. For backup power priority, Tesla Powerwall 3 leads the market. We recommend the right system based on your existing setup during the free survey.
Do I need planning permission for a battery in Burwell?
No. Domestic battery storage systems are permitted development and do not require planning permission. There are no restrictions on battery storage in conservation areas or listed buildings (unlike solar panels, which may require consent for listed buildings). Batteries are typically installed in a garage, utility room, or purpose-built external cabinet.
